Pre-installation
Checklist
Jobsite Inspection
Each unit has been inspected, tested
and operated at the factory by production and quality associates prior
to being crated for safe transit. However, rough handling or accidents
can occur resulting in damaged
equipment being delivered. Always
perform the following checks before
accepting a unit:
1. Do not sign the bill of lading
accepting the unit(s) until
inspection has been completed. Check for damage
promptly after the unit(s) are
unloaded. Once the bill of lading
is signed at the jobsite, the unit(s)
are now the property of the SOLD
TO party and future freight claims
MAY NOT be accepted by the
freight company.
2. Check the unit model numbers
on the bill of lading against
those ordered and received to
assure equipment is AS
ORDERED.
3. Check to assure that the refrig-
erant charge has been retained
during shipment by use of
gauges. Schrader taps are
located and labeled internal to
the cabinet. (See Figure 1).
Jobsite Storage
This unit is intended for indoor use
only. To protect the unit from damage
due to the elements, and to prevent
possible IAQ contaminant sources
from growing, the unit should be
stored indoors. If indoor storage is
not possible, the following provisions
for outdoor storage must be met.
1. Place the unit(s) on a dry sur-
face or raise above the ground
to assure adequate air circulation beneath the unit. This is to
assure that no portion of the unit
contacts standing water at any
time.
2. Cover the unit(s) with a water
proof tarp to protect them from
the elements.
3. Make provisions for continuous venting of the covered
units to prevent moisture from
standing on the unit(s) surfaces. Wet interior unit insulation
can become an amplification site
for microbial growth (mold) which

has been determined to be a
cause of odors and serious
health related indoor air quality
problems.
4. Store units in the normal UP
orientation. Storing units in this
manner maintains oil in the compressor.
5. Units may be stacked two high.
Important!
Equipment is shipped FOB (Free on
Board) at the manufacturer. Therefore, freight claims for damages
against the carrier must be initiated
by the receiver.
